Participants

Reaction Steps

Stirred a solution of tert-butyl (6-cyclopropyl-5-(1-(4-(trifluoromethyl)phenyl)-4,5-dihydro-5-oxo-1H-1,2,4-triazol-3-yl)pyridin-3-yl)methylcarbamate (0.100 g) in EtOC:HCl (5.0 mL) for 6 h at RT. Excess of solvent was removed and added DCM (5.0 mL), TEA (0.5 mL) and pivaloyl chloride (0.045 g) under nitrogen atmosphere o the reaction mixture. The reaction mass was stirred at RT for 4 h. Excess of solvent was removed under vacuum and the residue was diluted with water, extracted with EtOAC and concentrated to afford 0.020 g of the product. 1H NMR (300 MHz, DMSO d6): 0.98 (m, 4H), 1.12 (s, 9H), 2.73 (m, 1H), 4.27 (d, J=6.0 Hz, 2H), 7.78 (s, 1H), 7.85 (d, J=8.7 Hz, 2H), 8.13 (t, 1H), 8.19 (d, J=9.3 Hz, 2H), 8.40 (s, 1H), 12.75 (s, 1H); MS (m/z): 460.30 (M+H)+
